https://bugzilla.tianocore.org/show_bug.cgi?id=567 In function BasePrintLibSPrintMarker(), when processing ASCII format strings, if the format string walker pointer 'Format' is pointing at the end of the format string (i.e. '\0'), the following expression: *(Format + 1) will read an undefined value. Though this value won't affect the functionality, since it will be masked by variable 'FormatMask': (*(Format + 1) << 8)) & FormatMask (FormatMask is 0xff for ASCII format string) This commit adds additional logic to avoid reading undefined content.
